Shape of Topspin Groundstrokes

I learned this from the legendary Coach Steve Smith. The shape of the swing on a topspin ground stroke goes high-low-high and inside-out. This is a critical concept to understand from the beginning because it sets the stage for an efficient stroke. Later on it also leads to the development of lag or use of the stretch shortening cycle.


The Hips in the Kinetic Chain

The hips play a crucial role in transferring forces from the ground, up through the body and out into the racket. The role they play is a fundamental one in striking sports.

Here is a video of my 3 year-old son swinging a 26 inch racket two-handed. Without even knowing it he is learning how to use the hip in this manner.


Online Lessons

Teaching is simply information transfer.

Winning in tennis is a by-product of skills. Tennis strokes are mastered by learning how to perform them and then practicing, a lot.

When learning a skill like the forehand practice is slow and deliberate at first. When a fundamental baseline of skill is established then speed is increased and technique adapts in response to situations presented in the game.

I have had success getting players to acquire skills at home during the pandemic with nothing more than a Zoom call, sometimes an Eye Coach, and a routine of a few minutes of daily practice. I am even finding strokes can be mastered quickly at home because the player’s attention is 100% on their performance of the skill instead of where the ball goes after they hit it. The convenience of practicing at home for just a few minutes each day also makes consistently showing up to practice easy.

Above is are examples of online coaching. If you are interested please reach out to me for more information. One great thing that has come from this pandemic is that my skillset has improved and adapted. I am a better coach. I have acquired more coaching skills!


Practice Secrets

A few weeks ago I began an experiment. I wanted to teach myself to play tennis right handed. As a reference I am actually left handed in all I do.

Here is a video of my right and left comparisons.

I wanted to do this experiment for several reasons.

  1. A fellow coach @BigFootTennis can play righty and lefty which inspired me.
  2. I wanted to better relate to the kids I work with. I wanted to experience what it was like to learn a stroke from scratch.
  3. I wanted to see if I could discover a way to speed up the learning process.

So each night my 4 year old son and I head down to the garage and pull out the cars. I toss him some balls, he tries to hit me, he gets some coaching without knowing it and we have a lot of fun before bed. Once he loses interest I spend 5 minutes practicing with my right hand. Sometimes I practice with only a racket doing shadow swings and other times I use my Eye Coach (Coupon Code “SlezakPro” gets you a discount). My practice session is not long but I do it each and every day.

In a couple of few weeks I have seen tremendous growth. More importantly I have found out exactly how to speed up the process of acquiring a skill and it even works well in a pandemic.

  1. You must understand the movement. If you do not know what exactly to practice you are in a cycle of trial and error. That cycle wastes a lot of time. This is where a knowledgable coach whether in person or online via video analysis comes in. A coach is invaluable because they save you time and the only thing in life you cannot get any more of is time. Believe me I wish I knew then what I know now about tennis.
  2. You have to be consistent. I did not spend a ton of time each day practicing but I did show up everyday. By practicing just a few minutes each day it sends the brain a message that, “this is important and we want to become efficient at it.”
  3. You have to think about what you are practicing. I started slowly and deliberately focusing exclusively on getting the movement right. Gradually the motion got smoother and more coordinated. I noticed that when my toddler would distract me my practice was terrible but when I was thinking about what I was doing just for a few minutes it was obvious how good the practice was.
  4. It helped not to be on a tennis court. It helped tremendously to not have an end result to focus on. By not seeing a tennis ball flying through the air it allowed me to focus exclusively on my technique, which goes right back to number 3.

I am not surprised by any of the things I learned. In fact it only reinforces what I have known as a coach for years. But I hope learning to play with my opposite hand in my late 30’s inspires youngsters to practice just a few minutes each and every day wherever and however they can.

Here is a video where you can shadow swing right along with me.

Winter Tennis 2020 Information & Registration


We had a Baby Boy, Zander!

I am taking a little time off from coaching tennis to spend with my family.  However, once I get back I will continue with private lessons through the fall.  It worked extremely well this summer given the current situation and allows me more flexibility right now.  Once we get closer to the winter I’ll re-evaluate doing clinics once again.  If you are interested please email me info@alexslezak.com.


Video Analysis

I have spent more hours than I care to count developing strokes, studying technique and using video to enhance skill acquisition. The difference between good and elite technique is often small and takes a deep understanding of biomechanics. All elite groundstrokes and serves have the same fundamentals for power production, use of elastic energy and spin maximization. Although it may look like professional players at the top of the game have different mechanics they are all fundamentally the same. The way the human body (joints, muscles and nervous system) assemble a movement pattern makes it as unique to an individual as their DNA but the fundamentals remain the same.

The technology in our phones have made what was once impossible to see with the human eye as simple as using the slow motion function. With the knowledge it is now easier than ever to analyze technique, identify limiting factors and objectively measure improvement over time. The visual learning style also allows players to ā€œsee themselvesā€ instead of only being able to ā€œfeelā€ what they are doing on the court.

Important Summer Tennis Announcement

Unfortunately, with all that is going on with COVID-19 and the announcement that the high school campus will be closed this summer due to construction we will NOT be able to hold our regularly scheduled 2020 tennis camps.

As disappointing and unfortunate as that is I do have some good news. I will still be available for private lessons this summer. If this is something that would interest you please get in contact with me via email info@alexslezak.com or phone for the details.

Teaching all outdoor private lessons this summer will allow for the safest, most productive and flexible way to continue playing tennis.

I appreciate all the support over the years, stay safe and please keep in touch!
